【摘要】：隨著數(shù)字印刷時(shí)代的到來(lái)，機(jī)制文件在人們工作生活中所占的比例越來(lái)越大，司法鑒定工作中機(jī)制文件朱墨時(shí)序的鑒定問(wèn)題也逐漸成為文件檢驗(yàn)的重要組成部分。本實(shí)驗(yàn)研究從朱墨時(shí)序的影響因素入手，制作了200多張實(shí)驗(yàn)樣本，從文件印刷方式、印文材料、紙張、朱墨間隔時(shí)間等方面尋找其對(duì)朱墨時(shí)序的影響，，分析朱墨時(shí)序現(xiàn)象形成的原因，歸納總結(jié)朱墨時(shí)序的特征表現(xiàn)，探索朱墨時(shí)序的有效檢驗(yàn)方法，從理論和實(shí)踐上為以后的朱墨時(shí)序鑒定工作提供幫助。實(shí)驗(yàn)采用的研究方法主要是顯微鏡檢驗(yàn)方法和光譜檢驗(yàn)方法。顯微鏡檢驗(yàn)從文件朱墨交叉部位的墨跡分布入手，觀察文件朱墨交叉部位的顯微特征。光譜檢驗(yàn)方法主要使用文檢儀和多光譜成像系統(tǒng)，利用交叉部位的光譜特性變化觀察分析文件朱墨時(shí)序的光譜特征。實(shí)驗(yàn)研究發(fā)現(xiàn)光澤度變化是可用于判斷印刷文件朱墨時(shí)序的一種重要特征，如果朱墨交叉部位出現(xiàn)特殊顏色的光澤則可據(jù)此判斷文件與印文的形成順序，紅色印文的朱墨時(shí)序判斷以黃綠色光澤的出現(xiàn)為參考，藍(lán)色印文的朱墨時(shí)序判斷則以紫紅色光澤的出現(xiàn)為參考。實(shí)驗(yàn)還發(fā)現(xiàn)，在印泥蓋印的場(chǎng)合，覆蓋現(xiàn)象可以作為判斷文件與印文形成順序的重要參照；在印油蓋印完全的文件上，熒光、洇散度、油膜也可作為判斷文件朱墨順序倚靠的特征點(diǎn)。用多光譜成像系統(tǒng)實(shí)驗(yàn)發(fā)現(xiàn)，進(jìn)口印油在波長(zhǎng)600nm—650nm處比較交叉部位與打印字跡的光譜曲線，可較為準(zhǔn)確的判斷朱墨時(shí)序；國(guó)產(chǎn)印油在波長(zhǎng)600nm—700nm處比較交叉部位與打印字跡的光譜曲線，可以較為準(zhǔn)確的判斷朱墨時(shí)序。本實(shí)驗(yàn)的研究成果是從實(shí)驗(yàn)中歸納先朱后墨現(xiàn)象特征和先墨后朱現(xiàn)象特征，利用觀察到的特征和實(shí)驗(yàn)成果進(jìn)行綜合比較分析，可以比較準(zhǔn)確地判斷文件形成順序的正常與否，也為印刷文件和印章的先后順序判斷提供參考和借鑒。
[Abstract]:With the arrival of digital printing era, the proportion of mechanism documents in people's work and life is increasing, and the identification of mechanism documents' timing of Zhu and ink has gradually become an important part of document inspection. In this experiment, starting with the factors affecting the timing of Zhu ink, more than 200 experimental samples were made to find its influence on the timing of Zhu ink from the aspects of document printing, printing materials, paper, ink interval and so on. This paper analyzes the reasons for the formation of the time sequence phenomenon of Zhu ink, sums up the characteristics of the timing sequence of Zhu ink, probes into the effective testing method of the timing sequence of Zhu ink, and provides help in theory and practice for the time sequence identification work of Zhu ink in the future. The main research methods used in the experiment are microscope test and spectrum test. The microscopic characteristics of the ink-ink cross-section of the document were observed from the ink-ink cross-section distribution of the document by microscope. The spectral inspection method mainly uses the document detector and the multispectral imaging system. The spectral characteristics of the document Zhu and ink are observed and analyzed by using the spectral characteristics of the cross position. The experimental results show that the gloss change is an important feature for judging the timing of ink and ink in printed documents. If the gloss of special color appears in the cross part of ink and ink, it can be used to judge the order of formation of document and print. The timing judgment of red print is based on the appearance of yellowish green luster, while that of blue print is based on the appearance of purplish red luster. It is also found that the phenomenon of overlay can be used as an important reference for judging the order of the document and the print. The fluorescence, spread, and oil film can also be used as the characteristic points for judging the ink sequence of the document. By using multi-spectral imaging system, it is found that the imported printing oil can accurately judge the timing of ink by comparing the spectral curves between the cross position and the print handwriting at the wavelength 600nm-650nm. By comparing the spectral curves between the cross position and the printed handwriting at the wavelength 600nm-700nm, the domestic printing oil can accurately judge the time sequence of ink and ink. The research result of this experiment is to sum up the characteristics of first Zhu and then ink from the experiment, using the observed characteristics and experimental results for comprehensive comparison and analysis, we can accurately judge whether the order of file formation is normal or not. Also for printing documents and seals to judge the order of reference and reference.
